objectbox dart flutter desktop macos

Update: Since this answer was originally posted, ObjectBox now supports flutter-desktop out of the box. Refer to https://pub.dev/packages/objectbox#getting-started :

For sandboxed macOS apps: specify an application group. Check all macos/Runner/*.entitlements files if they contain a section with correct group ID info. Change the string value to the DEVELOPMENT_TEAM found in Xcode settings, plus an application-specific suffix, for example:

<key>com.apple.security.application-groups</key>
<array>
  <string>FGDTDLOBXDJ.demo</string>
</array>

Original answer:

ObjectBox Flutter desktop support is a work-in-progress, there's a tracking GitHub issue: https://github.com/objectbox/objectbox-dart/issues/166

For now, you have to add the ObjectBox native library libobjectbox.dylib manually using Xcode:

  • get the library from a GitHub release: https://github.com/objectbox/objectbox-c/releases/download/v0.13.0/objectbox-macos-universal.zip
  • Open the yourapp/macos/Runner.xcworkspace in Xcode.
  • Drag your precompiled library (libyourlibrary.dylib) into Runner/Frameworks.
    • Click Runner and go to the Build Phases tab.
      • Drag libobjectbox.dylib into the Copy Bundle Resources list.
      • Under Bundle Framework, check Code Sign on Copy.
      • Under Link Binary With Libraries, set status to Optional.
    • Click Runner and go to the General tab.
      • Drag libobjectbox.dylib into the Frameworks, Libararies and Embedded Content list.
      • Select Embed & Sign.
